Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements herein should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 , which is on file with the SEC. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of normal and recurring adjustments, necessary to present fairly the financial statements in accordance with GAAP. Intercompany balances and transactions between the Company and its subsidiaries have been eliminated in consolidation. Operating results for the three and nine months ended June 30, 2018 may not necessarily be indicative of results to be expected for any other interim period or for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Adoption of New Accounting Pronouncements Stock Compensation —The Company adopted the guidance in Accounting Standards Update ("ASU") No. 2016-09 Compensation - Stock Compensation - Improvements to Employee Share-Based Payments Accounting , on October 1, 2017. Under this standard, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $0.2 million cumulative effect adjustment to increase accumulated deficit as of October 1, 2017. ASU No. 2016-09 requires that all income tax effects related to settlements of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense (benefit). Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits reported in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied on a prospective basis to settlements occurring on or after October 1, 2017, and the impact of applying the guidance was not material to the consolidated financial statements for the three and nine months ended June 30, 2018 . Application of the guidance may result in fluctuations in the Company’s effective tax rate depending on how many options are exercised, how many restricted stock units vest and the volatility of the Company’s stock price. ASU No. 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. Previously, income tax benefits at settlement of an award were reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award’s vesting period. The Company has elected to apply the changes in cash flow classification on a prospective basis. Income Taxes — In March 2018, the FASB issued ASU No. 2018-05— Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (ASU 2018-05). The update provides guidance associated with the accounting and disclosures around the enactment of the Act and the Securities and Exchange Commission’s Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). This guidance was effective upon issuance and has been applied to the condensed consolidated financial statements and related disclosures beginning in the second quarter of fiscal 2018, see Note 10 for the disclosures related to this amended guidance.

Recent Accounting Pronouncement

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	3. Recent Accounting Pronouncements Revenue from Contracts with Customers— In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers Topic 606 (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The FASB has subsequently issued amendments to ASU No. 2014-09 that have the same effective date and transition date. ASU 2014-09, as amended, is effective for the Company’s fiscal year beginning October 1, 2018, and, at that time, the Company will adopt the new standard under the modified retrospective approach for contracts with customers. Under the modified retrospective approach, the guidance is applied to the most current period presented, recognizing the cumulative effect of the adoption change as an adjustment to beginning retained earnings. In fiscal 2017, the Company established a formal program and cross-functional implementation team to identify, design and implement changes to its accounting systems and policies and internal controls to support recognition and disclosure under the new standard. This process included a review of the requirements under the new standard compared to the current accounting policies for each of the Company’s revenue streams. As of the end of the third quarter of fiscal 2018, the Company substantially completed its review and does not expect a material impact on its consolidated financial statements upon implementation on October 1, 2018. The Company is currently preparing to implement changes to accounting policies and controls to support the new revenue recognition and disclosure requirements, which will be finalized during the fourth quarter of fiscal 2018. Leases — In February 2016, the FASB issued ASU No. 2016-02— Leases (Topic 842) (ASU 2016-02). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The standard will be effective for the Company on October 1, 2019. In July 2018, the FASB issued ASU No. 2018-11 — Leases (Topic 842): Targeted Improvements (ASU 2018-11) . Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. The Company is still evaluating the method of adoption. The adoption of this standard is expected to have a material impact on the Company’s financial position. As of June 30, 2018 , the Company had gross operating lease commitments of approximately $361 million . Upon adoption, a substantial portion of these lease commitments will be recorded at their net present value as a right of use asset and a lease obligation. Statement of Cash Flows— In November 2016, the FASB issued ASU No. 2016-18— Statement of Cash Flows (Topic 230): Restricted Cash . The update requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard will be applied using a retrospective transition method to each period presented and will be effective for the Company on October 1, 2018. As of June 30, 2018 and September 30, 2017 , the Company had total restricted cash of $50.3 million . Business Combinations — In January 2017, the FASB issued ASU No. 2017-01— Business Combinations (Topic 805): Clarifying the Definition of a Business . The update provides guidance to determine when an integrated set of assets and activities is not a business. When substantially all of the fair value of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, then the acquisition, or disposition, is not a business. The amendments in this update should be applied prospectively on or after the effective date. No disclosures are required at transition. The new standard will be effective for the Company on October 1, 2018. Early application of the amendments in this update is permitted for transactions meeting certain criteria. This standard could reduce the number of acquisitions that are treated as business combinations in the future.

Debt Disclosure [Abstract]
Long-Term Debt	4. Long-Term Debt As of June 30, 2018 and September 30, 2017 , the Company’s long-term debt consisted of the following: (in thousands) June 30, September 30, Term loan principal; principal and interest are due in quarterly installments through January 31, 2021 $ 701,978 $ 632,476 Original issue discount on term loan, net of accumulated amortization (1,130 ) (901 ) Deferred financing costs, net of accumulated amortization (4,042 ) (5,122 ) Senior secured revolving credit facility 9,500 — 706,306 626,453 Less current portion of the term loan 7,331 6,554 Less current portion of the senior secured revolving credit facility; matures on January 31, 2019 4,156 — Long-term debt $ 694,819 $ 619,899 Senior Secured Credit Facilities NMHI's senior credit agreement (the “senior credit agreement”), as amended, governs a $730.0 million (original $655.0 million term loan plus a $75.0 million incremental term loan funded on October 25, 2017) Tranche B term loan facility (the “term loan facility”), of which $50.0 million was deposited in a cash collateral account in support of the issuance of letters of credit under an institutional letter of credit facility (the “institutional letter of credit facility”), and a $160.0 million senior secured revolving credit facility (the “senior revolver”). The term loan facility matures on January 31, 2021, a portion of the commitments under the senior revolver matures on January 31, 2019 and a portion of the commitments under the senior revolver matures on January 31, 2021, as described below. All of the obligations under the senior secured credit facilities are guaranteed by NMHH and the subsidiary guarantors named therein. The senior credit agreement provides that NMHI may make one or more offers to the lenders, and consummate transactions with individual lenders that accept the terms contained in such offers, to extend the maturity date of the lender’s term loans and/or revolving commitments, subject to certain conditions, and any extended term loans or revolving commitments will constitute a separate class of term loans or revolving commitments. On October 24, 2017, NMHI entered into Amendment No. 6 to its senior credit agreement which provided for an incremental $75.0 million term loan. The net proceeds of the incremental term loan were used by the Company for the acquisition of Mentis Neuro Rehabilitation, LLC, with any excess proceeds used for general corporate purposes. On November 21, 2017, NMHI entered into Amendment No. 7 to its senior credit agreement which increased the aggregate revolving commitments from $120.0 million to $160.0 million and extended the maturity date for $90.0 million of the revolving commitments (the “Extended Revolving Commitments") to January 31, 2021. The terms of the remaining $70.0 million of the revolving commitments (the "Initial Revolving Commitments"), which mature on January 31, 2019, remain unchanged. All of the other terms of the Extended Revolving Commitments are identical to the Initial Revolving Commitments, except that the applicable margin for the Extended Revolving Commitments will decrease by 0.25% per annum when the Initial Revolving Commitments are terminated or expire. The senior revolver includes borrowing capacity available for letters of credit and for borrowings on same-day notice, referred to as the “swingline loans.” Any issuance of letters of credit or borrowing on a swingline loan will reduce the amount available under the senior revolver. As of June 30, 2018 , NMHI had $702.0 million of borrowings outstanding under the term loan facility, $9.5 million of borrowings outstanding under the senior revolver, $48.5 million of letters of credit issued under the institutional letter of credit facility and $2.9 million of standby letters of credit under the senior revolver. Borrowings under the term loan facility bear interest, at our option, at: (i) an alternate base rate ("ABR") equal to the greater of (a) the prime rate of Barclays Bank PLC, (b) the federal funds rate plus 1/2 of 1.0%, and (c) the Eurodollar rate for an interest period of one-month plus 100 basis points (provided that the ABR applicable to the term loan facility will not be less than 2.00% per annum), plus 2.00% ; or (ii) the Eurodollar rate (provided that the Eurodollar rate applicable to the term loan facility will not be less than 0.75% per annum), plus 3.00% . Borrowings under the revolving and swingline loans bear interest at our option at (i) an ABR equal to the greater of (a) the prime rate of Barclays Bank PLC, (b) the federal funds rate plus 1/2 of 1.0%, and (c) the Eurodollar rate for an interest period of one-month plus 100 basis points (provided that the ABR applicable to the term loan facility will not be less than 2.00% per annum), plus 2.25% ; or (ii) the Eurodollar rate (provided that the Eurodollar rate applicable to the term loan facility will not be less than 0.75% per annum), plus 3.25% . NMHI is also required to pay a commitment fee to the lenders under the senior revolver at an initial rate of 0.50% of the average daily unutilized commitments thereunder. NMHI must also pay customary letter of credit fees. The senior credit agreement requires NMHI to make mandatory prepayments, subject to certain exceptions, on a percentage of NMHI's annual Excess Cash Flow, as defined in the senior credit agreement. NMHI determines whether or not a mandatory prepayment is required at the end of each fiscal year. NMHI was not required to make a prepayment for the fiscal year ended September 30, 2017 . Covenants The senior credit agreement contains negative covenants, including, among other things, limitations on the Company’s ability to incur additional debt, create liens on assets, transfer or sell assets, pay dividends, redeem stock or make other distributions or investments, and engage in certain transactions with affiliates. The senior credit agreement contains a springing financial covenant. If, at the end of any fiscal quarter, the Company’s outstanding borrowings under the senior revolver exceeds 30% of the commitments thereunder, it is required to maintain at the end of each such fiscal quarter a consolidated first lien leverage ratio of not more than 5.00 to 1.00 . The springing financial covenant was not in effect as of June 30, 2018 or September 30, 2017 as the Company’s usage of the senior revolver did not exceed the threshold for each quarter. Derivatives On January 20, 2015, NMHI entered into two interest rate swap agreements in an aggregate notional amount of $375.0 million in order to reduce the variability of cash flows of the Company’s variable rate debt. NMHI entered into these interest rate swaps to hedge the risk of changes in the floating rate of interest on borrowings under the term loan. Under the terms of the swaps, NMHI will receive from the counterparty a quarterly payment based on a rate equal to the greater of 3-month LIBOR or 1.00% per annum, and NMHI will make payments to the counterparty based on a fixed rate of 1.795% per annum, in each case on the notional amount of $375.0 million , settled on a net payment basis. The swap agreements expire on March 31, 2020. The fair value of the swap agreements, which represents the price that would be received to transfer the agreement in an orderly transaction between market participants, was an asset of $5.8 million and a liability of $0.2 million as of June 30, 2018 and September 30, 2017 , respectively. Based on the timing of the associated cash flows, the fair value was split between current and long-term classification on the Company’s consolidated balance sheet in Prepaid expenses and other current assets and Other assets as of June 30, 2018 and in Other accrued liabilities as of September 30, 2017 . The fair value was determined based on pricing models and independent formulas using current assumptions. Hedge ineffectiveness, if any, associated with the swap is recorded as income or expense in the period incurred. During the three and nine months ended June 30, 2018 , the ineffective portion of gains resulting from changes in fair value was $0.1 million and $0.2 million which was recorded in Other income (expense), net. There was no hedge ineffectiveness recorded during the three and nine months ended June 30, 2017 . No amounts were excluded from ineffectiveness testing for the three and nine months ended June 30, 2018 and 2017 .

As of June 30, 2018 , the 2014 Plan authorized the issuance of up to 7,786,478 shares of common stock as stock-based awards, including incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), restricted stock units (“RSUs”) and performance based restricted stock units (“PRSUs”). Stock Options Stock option activity for the nine months ended June 30, 2018 is presented below: (in thousands, except share and per share amounts) Number of Weighted- Weighted- Aggregate Outstanding at September 30, 2017 877,781 $ 18.65 Granted 155,041 18.80 Exercised 17,608 17.00 Forfeited 36,381 18.64 Expired 23,081 19.87 Outstanding at June 30, 2018 955,752 $ 18.67 7.6 $ 13 Exercisable at June 30, 2018 566,980 $ 18.55 6.8 $ — Vested or expected to vest as of June 30, 2018 955,752 $ 18.67 7.6 $ 13 The Company utilizes the Black-Scholes valuation model for estimating the fair value of stock options. Options granted under the 2014 Plan during the nine months ended June 30, 2018 were valued using the following assumptions: 2018 Risk-free interest rate 2.22% - 2.74% Expected term 6 years Expected volatility 33.56% - 35.81% Expected dividend yield — % The Company recognizes the fair value of the stock option awards as stock-based compensation expense over the requisite service period of the individual grantee, which equals the vesting period. The total intrinsic values of options exercised was less than $0.1 million for the nine months ended June 30, 2018 . As of June 30, 2018 , there was $1.9 million of unrecognized compensation cost related to unvested stock options. This cost is expected to be recognized over a weighted-average period of 1.8 years. Restricted Stock Unit Awards (RSUs) Restricted stock unit activity for the nine months ended June 30, 2018 is presented below: Number of Restricted Stock Units Weighted Average Grant-Date Fair Value Non-vested units at September 30, 2017 677,406 $ 19.20 Granted 405,011 18.21 Forfeited 63,764 18.74 Vested 197,105 19.94 Non-vested units at June 30, 2018 821,548 $ 18.56 The fair value of each restricted stock unit was determined based on the Company's closing stock price on the date of grant. The Company recognizes the fair value of the RSUs as stock-based compensation expense over the requisite service period of the individual grantee, which equals the vesting period. The total fair values of RSUs that vested during the three and nine months ended June 30, 2018 was $0.1 million and $3.5 million , respectively. As of June 30, 2018 , there was $10.8 million of unrecognized compensation expense related to unvested restricted stock unit awards. This cost is expected to be recognized over a weighted-average period of 1.9 years. Performance Based Restricted Stock Units (PRSUs) During the nine months ended June 30, 2018 , the Company awarded 50,834 PRSUs. These PRSUs vest based upon the achievement of established performance targets over the three year performance period which ends September 30, 2020. The number of PRSUs that may vest varies between 0% - 200% based on the achievement of such goals. The PRSUs were valued at $18.76 per share based on the closing price of the Company’s common stock on the date of grant. To calculate compensation expense, the Company forecasts the likelihood of achieving the predefined performance targets and calculates the number of PRSUs expected to be earned. As of June 30, 2018 , the Company expects to recognize $1.0 million of stock-based compensation expense related to outstanding PRSUs based on the expected attainment levels. This cost is expected to be recognized over a weighted-average period of 2.0 years. A summary of PRSU activity for the nine months ended June 30, 2018 is as follows: Number of Performance Based Restricted Stock Units Weighted Average Grant-Date Fair Value Non-vested units at September 30, 2017 84,505 $ 19.85 Granted 50,834 18.76 Forfeited — — Vested — — Non-vested units at June 30, 2018 135,339 $ 19.44 Units expected to vest as of June 30, 2018 73,646 $ 19.09 Stock-based Compensation Expense The Company recorded stock-based compensation expense for stock options, RSUs and PRSUs under the 2014 Plan of $2.0 million and $5.8 million during the three and nine months ended June 30, 2018 , respectively, and $2.2 million and $6.6 million during the three and nine months ended June 30, 2017 , respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	9. Fair Value Measurements The Company measures and reports its financial assets and liabilities on the basis of fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level hierarchy for disclosure has been established to show the extent and level of judgment used to estimate fair value measurements, as follows: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Significant other observable inputs (quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability). Level 3: Significant unobservable inputs for the asset or liability. These values are generally determined using pricing models which utilize management estimates of market participant assumptions. Valuation techniques for assets and liabilities measured using Level 3 inputs may include methodologies such as the market approach, the income approach or the cost approach, and may use unobservable inputs such as projections, estimates and management’s interpretation of current market data. These unobservable inputs are only utilized to the extent that observable inputs are not available or cost-effective to obtain. A description of the valuation methodologies used for instruments measured at fair value as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. The following table sets forth the Company’s assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2018 .

(in thousands) Total Quoted Market Prices (Level 1) Significant Significant Unobservable Inputs (Level 3) Liabilities Interest rate swap agreements $ 153 $ — $ 153 $ — Interest rate-swap agreements. The Company’s interest rate-swap agreements are classified within Level 2 of the fair value hierarchy. Based on the timing of the associated cash flows, the fair value of the swap agreements was recorded in Prepaid expenses and other current assets, Other assets, or Other accrued liabilities in the Company’s consolidated balance sheets. The fair value of these agreements was determined based on pricing models and independent formulas using current assumptions that included swap terms, interest rates and forward LIBOR curves and the Company’s credit risk. The following table presents a summary of changes in fair value of the Company’s Level 3 liabilities (acquisition related contingent consideration) measured on a recurring basis for the nine months ended June 30, 2018 .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes The Company’s effective income tax rate for the interim periods is based on management’s estimate of the Company’s annual effective tax rate for the applicable year. It is also affected by discrete items that may occur in any given period. The rates differ from the federal statutory income tax rate primarily due to state income taxes and nondeductible permanent differences such as meals and nondeductible compensation. For the three and nine months ended June 30, 2018 , the Company had a provision from income taxes of $4.7 million , or a 32.7% effective income tax rate, and a benefit of $2.4 million , or a (16.8)% effective income tax rate, respectively. This compares to a provision for income taxes of $4.4 million , or a 37.5% effective income tax rate, and $10.6 million , or a 38.5% effective income tax rate, for the three and nine months ended June 30, 2017 , respectively. The benefit from income taxes for the nine months ended June 30, 2018 was primarily due to revaluing of the Company’s deferred tax liabilities as a result of the lower corporate tax rate established by the Tax Cuts and Jobs Act (the “Tax Act”) enacted in the first quarter of fiscal 2018. The Tax Act significantly revises corporate income tax law by, among other things, lowering the corporate income tax rates from 35% to 21%. Under GAAP, deferred taxes must be adjusted for enacted changes in tax laws or rates during the period in which new tax legislation is enacted. ASU 2018-05 allows a company to record a provisional amount when it does not have the necessary information available, prepared, or analyzed in reasonable detail to complete its accounting for the changes in the Tax Act. The measurement period ends when the company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year from the date of enactment of the Tax Act. As of June 30, 2018, the Company has not completed the accounting for the tax effects of the enactment of the Tax Act; however, in certain cases, as described below, the Company has made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax. These amounts may require further adjustments as a result of additional future guidance from the U.S. Department of the Treasury, changes in assumptions, and the availability of further information and interpretations. For the items for which the Company was able to determine a reasonable estimate, a provisional tax benefit of $6.7 million was recognized which is included as a component of income tax expense for the nine months ended June 30, 2018. The accounting for the tax effects of the enactment of the Tax Act will be finalized during the fourth quarter of fiscal 2018. The Company remeasured certain deferred tax assets and liabilities based on an estimate of the rates at which they are expected to reverse in the future. However, the Company is still analyzing certain aspects of the Tax Act and refining calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. Additionally, the estimates for when timing differences will reverse could differ from actual results at year end, impacting the provisional tax benefit. The Company files a federal consolidated return and files various state income tax returns and, generally, is no longer subject to income tax examinations by the taxing authorities for years prior to September 30, 2015. The Company did not have a reserve for uncertain income tax positions at June 30, 2018 and September 30, 2017 . The Company does not expect any significant changes to unrecognized tax benefits within the next twelve months. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits as charges to income tax expense.

Commitments and Contingencies Disclosure [Abstract]
Other Commitments and Contingencies	14. Other Commitments and Contingencies The Company is in the health and human services business and, therefore, has been and continues to be subject to numerous claims alleging that the Company, its employees or its independently contracted host-home caregivers (“Mentors”) failed to provide proper care for an individual served by the Company. The Company is also subject to claims by these individuals, its employees, its Mentors or community members against the Company for negligence, intentional misconduct or violation of applicable laws. Included in the Company’s recent claims are claims alleging personal injury, assault, abuse, wrongful death and other charges. Regulatory agencies may initiate administrative proceedings alleging that the Company’s programs, employees or agents violate statutes and regulations and seek to impose monetary penalties on the Company. The Company could be required to incur significant costs to respond to regulatory investigations or defend against civil lawsuits and, if the Company does not prevail, the Company could be required to pay substantial amounts of money in damages, settlement amounts or penalties arising from these legal proceedings. The Company is also subject to potential lawsuits under the False Claims Act and other federal and state whistleblower statutes designed to combat fraud and abuse in the health care industry. These lawsuits can involve significant monetary awards that may incentivize private plaintiffs to bring these suits. If the Company is found to have violated the False Claims Act, it could be excluded from participation in Medicaid and other federal healthcare programs which would have a material adverse effect on the business. The Patient Protection and Affordable Care Act provides a mandate for more vigorous and widespread enforcement activity to combat fraud and abuse in the health care industry. The Company is also subject to employee-related claims under state and federal law, including claims for wage and hour violations under the Fair Labor Standards Act or state wage and hour laws, and claims for discrimination, wrongful discharge or retaliation. The Company currently has two pending complaints in California state court that allege certain wage and hour violations of California labor laws and seek to be designated as class-action. Two additional wage and hour claims have been settled, one of which was settled and approved by the court on January 31, 2018 and and one of which has been preliminarily approved by the court. Final approval and payment for this claim is expected in September 2018. The Company’s policy is to accrue for all probable and estimable claims using information available at the time the financial statements are issued. Actual claims could settle in the future at materially different amounts due to the nature of litigation.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements herein should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 , which is on file with the SEC. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of normal and recurring adjustments, necessary to present fairly the financial statements in accordance with GAAP. Intercompany balances and transactions between the Company and its subsidiaries have been eliminated in consolidation. Operating results for the three and nine months ended June 30, 2018 may not necessarily be indicative of results to be expected for any other interim period or for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Adoption of New Accounting Pronouncements Stock Compensation —The Company adopted the guidance in Accounting Standards Update ("ASU") No. 2016-09 Compensation - Stock Compensation - Improvements to Employee Share-Based Payments Accounting , on October 1, 2017. Under this standard, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $0.2 million cumulative effect adjustment to increase accumulated deficit as of October 1, 2017. ASU No. 2016-09 requires that all income tax effects related to settlements of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense (benefit). Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits reported in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied on a prospective basis to settlements occurring on or after October 1, 2017, and the impact of applying the guidance was not material to the consolidated financial statements for the three and nine months ended June 30, 2018 . Application of the guidance may result in fluctuations in the Company’s effective tax rate depending on how many options are exercised, how many restricted stock units vest and the volatility of the Company’s stock price. ASU No. 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. Previously, income tax benefits at settlement of an award were reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award’s vesting period. The Company has elected to apply the changes in cash flow classification on a prospective basis. 3. Recent Accounting Pronouncements Revenue from Contracts with Customers— In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers Topic 606 (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The FASB has subsequently issued amendments to ASU No. 2014-09 that have the same effective date and transition date. ASU 2014-09, as amended, is effective for the Company’s fiscal year beginning October 1, 2018, and, at that time, the Company will adopt the new standard under the modified retrospective approach for contracts with customers. Under the modified retrospective approach, the guidance is applied to the most current period presented, recognizing the cumulative effect of the adoption change as an adjustment to beginning retained earnings. In fiscal 2017, the Company established a formal program and cross-functional implementation team to identify, design and implement changes to its accounting systems and policies and internal controls to support recognition and disclosure under the new standard. This process included a review of the requirements under the new standard compared to the current accounting policies for each of the Company’s revenue streams. As of the end of the third quarter of fiscal 2018, the Company substantially completed its review and does not expect a material impact on its consolidated financial statements upon implementation on October 1, 2018. The Company is currently preparing to implement changes to accounting policies and controls to support the new revenue recognition and disclosure requirements, which will be finalized during the fourth quarter of fiscal 2018. Leases — In February 2016, the FASB issued ASU No. 2016-02— Leases (Topic 842) (ASU 2016-02). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The standard will be effective for the Company on October 1, 2019. In July 2018, the FASB issued ASU No. 2018-11 — Leases (Topic 842): Targeted Improvements (ASU 2018-11) . Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. The Company is still evaluating the method of adoption. The adoption of this standard is expected to have a material impact on the Company’s financial position. As of June 30, 2018 , the Company had gross operating lease commitments of approximately $361 million . Upon adoption, a substantial portion of these lease commitments will be recorded at their net present value as a right of use asset and a lease obligation. Statement of Cash Flows— In November 2016, the FASB issued ASU No. 2016-18— Statement of Cash Flows (Topic 230): Restricted Cash . The update requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard will be applied using a retrospective transition method to each period presented and will be effective for the Company on October 1, 2018. As of June 30, 2018 and September 30, 2017 , the Company had total restricted cash of $50.3 million . Business Combinations — In January 2017, the FASB issued ASU No. 2017-01— Business Combinations (Topic 805): Clarifying the Definition of a Business . The update provides guidance to determine when an integrated set of assets and activities is not a business. When substantially all of the fair value of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, then the acquisition, or disposition, is not a business. The amendments in this update should be applied prospectively on or after the effective date. No disclosures are required at transition. The new standard will be effective for the Company on October 1, 2018. Early application of the amendments in this update is permitted for transactions meeting certain criteria. This standard could reduce the number of acquisitions that are treated as business combinations in the future.
